fiHAY-ELEVATOR AND TRACK FOR-THE SAME.

SPECIFICATION forming part of Letters Patent No. 362,307, dated May 3,1887.

Application filed December 21, 1886. Serial No. 222,189.

generally been formed of two parallel bars and v I complicated in form,necessitating the use of more rollers than absolutely necessary, andrendering it difficult to remove the elevator from the track-whennecessary, and difficult to construct.

The object of my present invention is to provide a metal track, cheapand substantial in construction, which may be readily suspended in anybuilding, and one in which the elevator to be used shall be of suchformation that its 2 5 parts shall be reduced to a minimum.

A further object is to provide a light and inexpensive elevator whichmay be easily removed from the track, but which shall not be liable toaccidental displacement.

With these ends in view my invention consists in certain features ofconstruction and combinations of parts, as will be hereinafter fullydescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in perspective of myimproved track and elevator, the latter being in the position ofdropping its load. Fig. 2 is an end view of track and section of thecarrier, partly in section.

A represents the track or rail, preferably similar in form to theordinary railway-track, but smaller and lighter, having the lateralflanges a a on the upper edge, so that its upper face is flat, while thelower edge, b, is .5 flanged and rounded in order to increase itsstrength; but this construction is by no means necessary, and the railmight be T-shaped in section.

The hangenhooks B are either formed to 50 clasp the lower edge, I), ofthe track when the latter is rounded or when the track is T-shaped.

A desirable means of adjustment is by the use (No model.)

of an adjusting screw in the hanger-hook, the object to be attainedbeing to admit of the hangers being moved or shifted along the I trackshould it be necessary to vary its point of support. The hanger hooks Bare bent laterally through the middle portion, 0, sufficiently to leaveconsiderable space between itself and the track, and its upper endtermi- 6o nates in a forwardly or backwardly turned book, a, theposition of which is directly over the longitudinal center of the trackor rail A. A U-shaped iron, 0, is secured to the rafters, and the hook cis adapted to rest therein.

D represents the carriage or traverser of the elevator, mounted on thetrack A by means of the flanged rollers E, preferably two in number. Thewidth of the rollers E is sufficient to throw the flanged portion e onthe opposite 7o edge from the body of the carriage D, and hence on thesame side with the hangers, yet adapted to slide by them withouttouching the latter.

The flange 0 acts as a guide, preventing the carriage from rolling offits track laterally, while a lug, f, formed integral with one side ofthe carriage, is located beneath the upper flange of the track or rail,preventing the can, riage from upwardly jumping the track. A pair ofpulleys, F, in the lower end of the carriage receive the elevating-ropeG between them, one end of this rope being secured to the pivotedelevator-holder H, whereon the elevator pulley and hook I are held. TheV- shaped latch'J is pivoted to the carriage at point 5, its lower endengaging with the lug j to hold the elevator-holder H in anapproximately horizontal adjustment, while the upper end of the latchengages with the rounded slot of the cam-block K, removably secured tothe rail or track A over the point at which it is desirable to elevatethe load to the elevator. Obviously this cam-block K may be moved tovarious points on the track after loosening the 5 adj usting-screw 7c.

The operation is as follows: The elevatingrope G is drawn until thepulley and hook I are elevated and slid onto the elevator-holder H, towhich the rope is attached, causing the [O0 holder to assume ahorizontal position, where it is held by the engagement of the lower endof latch J with the lug j until it returns to the point where the loadis to be lowered, when the upper end of latch Jis forced into engagementwith the cam groove or block K, which forces the latch upward out ofengagement with lug j, allowing the holder H to tip, the pulley and hookI descending vertically. To return the elevator and carriage, it issimply necessary to pull the end of the rope G, the other partsoperating automatically.

It is evident that other elevators might be used with this track, andthat slight changes might be resorted to in the form and arrangement ofthe several parts described without departing from the spirit and scopeof my invention; hence I do not wish to limit myself 1t)o the particularconstruction herein set forth;

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. The combination, with a rail or trackand acam-block, ofa carrier mounted on the rail or track, anelevatorholder, substantially as described, pivoted to the carrier, anda latch pivoted to, the carrier and adapted to lock said holder in anelevated position.

2. The combination, with a rail consisting of a web or a body and twolaterally-projecting horizontal flanges and hangers secured to the webof the rail, of a carriage having pulleys adapted to travel on thetrack, the said pulleys having flanges adapted to engage the side edgeof the track farthest from the car riage and the latter having aprojection adapted to rest under and in close proximityto the flange onthe side adjacent to the carriage, substantially as set forth.

3. The combination, with a metallic rail or track having the horizontallaterallyprojeeting flanges, hangers for supporting the rail, and thecam-block secured to the rail, of a carrier mounted on wheels, thelatter having flanges on one side adapted to engage one side edge of therail, the carrier having a projection adapted to rest under the oppositeside edge of the rail, and a latch pivoted to the carrier and adapted byengagement of the cam-block to release the block, substantially as setforth.

4. The combination, with a flanged rail, the

supporting hanger-hooks, and the cam-block adj ustably secured to therail, of a hay-eleva tor mounted on the rail, a block or elevatorsupport or holder pivoted to the carriage and adapted to be held in anelevated position by alateh, and a latch pivoted to the carrier, adaptedbyits. engagement with the cam-block to release the block or elevatorholder or support, substantially as set forth.

The COIIlbillttbiOll, with a rail and a cambloek seeu red thereto, ofallay-carrier adapted to travel on the rail, an elevator-holder looselysecured to the carrier, an elevating-rope attached to theelevatorholder, a block or elevator mounted on the rope and adapted toengage the elevator-holder, and a latch for locking said holder in anelevated position, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
